How do I install missing intermediate certificates to resolv

The process depends on your web server. For Apache, you typically concatenate the primary certificate and the intermediate certificates into a single `.crt` or `.pem` file and configure the `SSLCertificateFile` directive. For Nginx, you would also concatenate these certificates, placing the primary certificate first followed by the intermediate certificates in the combined file. The CA usually provides instructions on which intermediate certificates to include and how to order them.
